In 2369, Rager was serving aboard the Enterprise-D when the ship discovered a Dyson Sphere. She piloted the ship out of the sphere by executing a 90-degree roll to slip out of the quickly closing bay doors. (TNGepisode: "Relics")

Later that year, Rager was one of several crewmembers to be abducted by solanagen-based lifeforms and had several experiments conducted on her. Fortunately, she was rescued by Commander Riker. (TNGepisode: "Schisms")

After the Titan entered orbit of New Erigol, Rager received and played the message from the Caeliar indicating the ship could not depart the planet and would have no direct contact with the away team. Later, when the Titan attempted to send a strike team inside the sphere, Rager was responsible for charging the inverters, even though the attempt was a failure. (ST - Destinynovel: Mere Mortals)

After former Earth Starfleet Captain Erika Hernandez offered to help the Titan escape New Erigol and the Caeliar, Rager was gently nudged away from the operations console by Hernandez, who programmed their deflector to emit a phase-shifted soliton field to control the subspace aperture. As the Titan engaged its engines, Captain Riker ordered Rager to divert all available power to the deflector.

In 2386, Rager was promoted to lieutenant commander. She also was heavily involved in the Titan's conflict with the Solanae, who had previously abducted her while she served on the Enterprise-D seventeen years earlier. (TTNnovel: Sight Unseen)
